I noticed a youtube video, where Thomas Warren Campbell, a physicist and author of the book trilogy My big TOE the last standing for Theory of Everything and apparently he also works for NASA, deducts some very disturbing things from a certain double slit experiment. Here it is, I marked the beginning where the big words start rolling, just put it behind the youtube url ... watch?v=GrL9kBx5jS4&feature=player_detailpage#t=714s To summarize he makes the following assertions: 1. Reality is not objective 2. When used, a measuring device will not disturb the measurement of photons in the Double Slit Experiment. Something else does it. 3. A conscious observer by observing the particle [retroactively] changes it's distribution on the "wall". If a conscious observer, knows, just knows where the particle went, by looking at the measurement data (I remind you in his model the measurement does not interfere with the photons) he will alter what he is about to see when he checks the "wall" data. I have read the Steinberg Double Slit Experiment from Science june 2011 and it seems very clear from that paper that one can measure the photon and get a diffraction pattern. So that seems to demonstrate that Thomas' whole premise is wrong, that the measurement truly was disturbing that which was being measured, until the Steinberg team found a way. Well, is this guy Tom Campbell just full of it or ... I don't know why a physicist that works for NASA would jump to such wild conclusions. I don't feel good dismissing any idea without further review... Maybe I just don't get it? Please help me get my head around this!
